N2 - We demonstrate basic operation of Brillouin optical correlation-domain reflectometry (BOCDR) based on an external modulation scheme, which can mitigate three demerits of a conventional direct modulation scheme. A 0.8 m long strain in a 2.8 m long silica fiber is successfully detected in a distributed manner. This scheme can be employed not only in BOCDR but also in Brillouin optical correlation-domain analysis.
